The building now stands as a fully modernized, amenity-rich, and highly desirable Class A office destination. The successful leasing activity with firms like DAZN and Anchorage Digital proves that quality space with unmatched indoor and outdoor amenities is still a winning formula in New York City's competitive commercial real estate landscape.
